Calculate Attenuation Circuit ( L-Pad )
Speaker impedance:
Ohm
Wanted Attenuation:
dB
Series resistance R
_{1}
:
Ohm
Parallel resistance R
_{2}
:
Ohm
Calculate here the attenuation and new driver-impedance of an existing attenuation circuit or with resistors different then calculated before.
Important:
Impedance from this circuit has to be as close as possible to the original driver impedance. If the difference is >0.25 ohm the filter function is deviating of the computations.
Enter R
_{1}
, R
_{2}
and the driver impedance.
The impedance and attenuation of the circuit including the driver will be calculated.
This can be usefull if you have to use resistors with a different values then calculated for the attenuation circuit.
Driver impedance:
ohm
Series resistance R
_{1}
ohm
Parallel resistance R
_{2}
ohm
Driver impedance (incl. attenuator):
ohm
Attenuation:
dB
Driver impedance difference:
ohm
Message:
The changed Driver impedance is important to calculate the Crossover Network!
